HP Serviceguard Metrocluster Verifying the status of Continentalclusters daemons, # cmdeleteconcl

The verification is done based on the stable clusters' environment and the proper functioning of the network communication. In case the network communication between clusters can not be established or the cluster or package status cannot be determined, manual verification must be done to ensure that the operation to be performed on the target package will not have a conflict with other packages configured in the same recovery group.

Verifying the status of Continentalclusters daemons

Use the ps command to verify the status of the Continentalclusters monitor daemons cmclsentryd, which must be running on the cluster node where the monitor package is running.

For Example:

# ps —ef grep cmclsentryd

Use the ps command to verify the status of the Continentalclusters daemon cmclapplyd on all the nodes in Continentalclusters. This daemon is started as part of the Continentalclusters installation and is required for applying the Continentalclusters configuration.

# ps -ef grep cmclapplyd

Renaming the Continentalclusters

To rename an existing Continentalclusters:

1.Remove the Continentalclusters configuration.

# cmdeleteconcl

2.Edit the CONTINENTAL_CLUSTER_NAME field in the configuration ASCII file, and run the cmapplyconcl command to configure the Continentalclusters with a new name.
